URL is not same as PHP $_SERVER['DOCUMENT_ROOT']

Question

I am using Oracle VM VirtualBox + Vagrant + CentOS 7.0 + PHP.

When i enter the page http://192.168.33.10/public/index.php :

header('Location: '.$_SERVER['DOCUMENT_ROOT'] .'/public/index.php');

This should redirect to public/public/index.php , but I don't know why it redirects to /vagrant/public/public/index.php .

How can I fix it?

Answer 1

It's just wrong! First of all you use header() in a wrong way

correct:

header('Location: URL');

And you use the wrong variable:

$_SERVER['DOCUMENT_ROOT']

returns the absolute local path on the machine.

$_SERVER['SERVER_NAME'] would fit better, but remember addings http/https in front of it

BUT:

You don't need to add the current servername - Just add the path

header('Location: /public/index.php');

This will always redirect to HTTP(S)://YOURSERVER/public/index.php

And you can also use relative paths, just remove the trailing slash
